    Problem Text
    This test may fail if the terminal the test is run on does not
    support setting split input/output baud rates.

    POSIX.1 and XPG4 do not mandate support for split input/output baud
    rates for the tcsetattr system interface (see 1003.1b-1993 7.2.1.2,
    page 183 and XSH4 Version 2, page 653).
    .br
    POSIX.2 and XPG4 do not mandate support for split input/output baud
    rates for the stty utility (see 1003.2-1992 4.49.41., page 438 and
    XCU4 Version 2, page 665). Additionally, "It is unspecified whether
    stty will report an error if an attempt to set a Control Mode fails".
    In the case where the underlying HW (asynchronous tty adapter) does
    not support split speeds, it is not possible to construct a test
    which is guaranteed to work under these conditions.
    .br
    Making the assumption that the majority of asynchronous tty HW does
    not support split baud rates, because the functionality is not really
    required for alpha-numeric terminals, and in view of the fact that
    there is no current interpretation for this problem, I suppose that
    test suite reports have been produced using work station type
    platforms where the HW does have support. Most of our HW platforms
    do not have native VGA.
    .br
    Running VSC4 on a pseudo-tty (e.g., rlogin), this stty command is
    supported, but it is not, I believe, acceptable to show conformance
    without running on a classical, asynchronous tty.
    Test Output
